bspConfiguration - NUCLEO-G474RE
================================

Overview
--------

The ``bspConfiguration`` module contains hardware-specific configuration for the
NUCLEO-G474RE evaluation board. Driver logic is separated from its configuration
so that users can customise a project for different boards or pin assignments
without modifying driver source code.

The STM32G474RE platform currently exposes a minimal set of BSP peripherals:

- **bspUart** - USART2 configuration (ST-LINK Virtual COM Port on PA2/PA3).
- **bspStdIo** - Standard I/O bridge that routes ``putByteToStdout`` /
  ``getByteFromStdin`` through the configured UART instance.

.. note::

   The ADC, PWM, and digital I/O configuration modules demonstrated by the
   S32K148EVB reference application are not yet ported to this platform.
   They are demonstration features independent of CAN and should be added
   following the same configuration pattern in a future change.
